If you're planning to preserve your fertility through egg or embryo freezing, one of the most impactful steps you can take is to optimize your health—particularly your weight—before starting the stimulation process. Emerging evidence suggests that GLP-1 medications, such as semaglutide and liraglutide, can play a role in this optimization.

Why Weight Matters for Fertility

Both the American Society for Reproductive Medicine (ASRM) and the American College of Obstetricians and Gynecologists (ACOG) emphasize the importance of achieving a healthy weight when preparing for fertility treatments. Obesity has been linked to lower ovarian reserve, impaired embryo quality, and increased miscarriage risk. ASRM's 2021 Committee Opinion on obesity and reproduction underscores that weight loss can improve ovulatory function and response to ovarian stimulation in assisted reproductive technology (ART) cycles.

ACOG's guidelines also support weight management as a component of fertility optimization. While specific recommendations may vary, the general consensus is that achieving a healthy weight can enhance fertility outcomes and reduce complications during ART procedures. ACOG Committee Opinion 2021

When Should You Begin Weight Loss?

If you're considering egg or embryo freezing, it's advisable to start weight management efforts at least 3–6 months before beginning the stimulation cycle. This timeframe allows your body to adjust and can lead to improved ovarian response and better quality eggs. Rapid or extreme weight loss should be avoided, as it can disrupt hormonal balance and negatively impact fertility.

The Role of GLP-1 Medications

GLP-1 receptor agonists, such as semaglutide and liraglutide, have gained attention for their effectiveness in promoting weight loss. These medications work by enhancing insulin sensitivity, reducing appetite, and slowing gastric emptying. Clinical studies have demonstrated significant weight reduction in individuals with obesity, and these benefits are achieved without the need for extreme dietary restrictions or intensive exercise regimens.

For individuals preparing for egg retrieval, GLP-1 medications may offer several advantages:

Improved Ovarian Response: By achieving a healthier weight, ovarian stimulation may be more effective, leading to a better response during egg retrieval.
Enhanced Egg Quality: Weight loss can improve hormonal balance, potentially leading to higher quality eggs and embryos.
Reduced Risk of Complications: Maintaining a healthy weight can decrease the likelihood of complications during the ART process.

Considerations Before Starting GLP-1 Medications

Before initiating GLP-1 therapy, consult with your fertility specialist to determine if it's appropriate for you. These medications are generally well-tolerated, but they may not be suitable for everyone. Your healthcare provider will consider factors such as your medical history, current medications, and specific fertility goals to develop a personalized plan.

Conclusion

Optimizing your weight before undergoing egg or embryo freezing can significantly enhance your fertility outcomes. GLP-1 medications offer a promising option for achieving sustainable weight loss, thereby improving ovarian response and egg quality. By working closely with your fertility team, you can develop a comprehensive plan that aligns with your reproductive goals and overall health.
